Hi, I think I run into the same problem as described in a thread on the lkml: " bio too big device md1 (16 > 8)" Message-Id <87irc84bcq.87hcrs4bcq@xxxxxxxxxxxxxxxxxxxxx> http://lkml.org/lkml/2007/4/7/81 A related thread on dm-devel about a patch that probably doesn't help: " [2.6.22 PATCH 01/26] dm: merge max_hw_sector" http://www.redhat.com/archives/dm-devel/2007-May/msg00007.html Any news regarding this one? Should I file a bug on http://bugzilla.kernel.org/ ? (It seems there is no entry yet) Anything I could do to help fix this problem? Thanks Jens PS: if I have a LVM snapshot the message disappears -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
